. specification.

My invention relates to vapor-engines of the kind wherein power isderived from the explosion of a mixture of air and a combustible vaporor gas in a cylinder. I may utilize any vapor or gas, but preferably Iemploy the vapor of kerosene, benzine, or analogous hydro-' carbons.

The .present invention especially concerns the construction andoperation of mechanism for delivering the liquid hydrocarbon to thevaporizer, the regulation of the quantity of the same so delivered, itsvaporization and intermixture with air, and final ignition.

I will describe a vapor-engine embodying my improvement and then pointout the novel features in a claim.

In the accompanying drawings, Figure 1 is a side View of an engineembodying .myimprovement, certain parts, however, being omitted. Fig. 2is a sectional view onthe Fig. 3 is a sectional view Fig. 4 is alongitudi-' line 2 2 of Fig. 1. in the line 3 3 of Fig. 1. nal sectionof a heater embodied in the improvement. Fig. 5 is a top view of thesame. Similar lettersof reference designate corresponding parts in allfigures.

A designates the cylinder of an engine. It may or may not be providedwith chambered walls to receive circulating cooling-water.

The cylinder may be provided with a piston and piston-rod of the usualtype, and a suitable connecting-rod and crank-shaft may be supplied forthe purpose of transmitting power, or the piston may be what isordinarily known as the trunk-piston. These parts form no part of myinvention, and as they may be of any approved type I have not consideredit necessary to illustrate the same. B is is a rod extending lengthwiseof the engine and deriving a longitudinally-reciprocating motiontherefrom. For, instance, it may be connected with an eccentric-strap,the latter encircling an eccentric actuated by the engine in a mannerwell known, or it may be operated by gears deriving motion from thecrank-shaft of the engine. At one end this rod B is connected'with'alever b, from which a suitable'slide-valve is operated to control theexhaust-opening for the cylinder. As these parts may also be'of anyapproved or suitable construction, I have not thought it necessary toillustrate them. The rod B also in the present instance serves tocontrol the operation of a governor O. A block 0 is provided with aset-screw by which it may be attached at any point of the rod B.

O is the fulcrum-point of an elbow-lever comprising adownwardly-projecting arm 0 and a horizontally-projecting arm 0. Aweight 0 is carried by the arm 0. Preferably it will be adjustable alongthe arm 0. To this end the weight 0 may so engage with the arm 0 as tobe capable of sliding along the same, and a nut a may be supplied foradjusting purposes. The free end of the arm 0 is provided with a catch owhose purpose will appear presently.

. D is a bracket attached to the side of cylinder A and provided with asuitable appurtenance carrying the fulcrum-pin E for an elbow-leverwhose downwardly-projecting arm E is pivoted to a slide E carried inguides 4 6, supported by a bracket 6. from the upper surface of theslide F. andis adapted to be engaged by the catch c atthe endof arm e.

, F. is a spring attached to the arm E and a stationary piece, by whichthe arm E is urged toward the inner end of its movement.

The outer end of the bracket e projects upwardly under the arm 0 and isadapted to err-- gage with a cross-pin 1 extending from the .armc,thereby lifting the latter as the "slide E is drawn forward by thecatch0 thereby releasing the slide from the catch, which thereupon returns toits normal position under the influence of spring E F is a supply-tankfor the kerosene ben zine, or other liquid employed. It is provided atits lower portion with an upwardly-closing valve F, supported from abridge-piece F.

A lug 6 projects G is a cylinder provided with a piston G. A piston-rodG projects upwardly through the cylinder-cover and is provided with acollar g, which may be made adjustable. A spring g is interposed betweenthe collar 1 and the cylinder-head to hold the piston in an elevatedposition.

ll is a projection carried by the bracket 1), havin an interiorpassage-way controlled by a downwardly-closing valve II. The chambersand passage-ways of the projection ll, the cylinder G, and the reservoirF are in direct communication with each other through suitablepassage-ways.

The second arm 11 of the elbowdever, of which arm E constitutes onemember, extends horizontally from the fulcrum-pin E and is provided atits outer end with an adjustable stop 11 for coacting with the pistonrodG of the piston G. The stop is here shown to be in the form of a screw,which may be provided with a lock-nut. It is evident that when thepiston G is forced downward valve F will close, while the passagewaycontrolled by valve II. will be unobstru cted.

1 is the vaporizer, here shown to be in the form of a cup provided withscrew-threads, by which it may be attached to the bracket .l). Theinterior opening of the vaporizer I is continued upward through thebracket D and is extended through a lateral passageway I and a suitablechamber in the cylinderwall to the cylinder end. The interior openin gof the vaporizer I is closed to a movement of the motive fluid from thepassage-way I backward to the vaporizer by suitable valve 1 I is anannular chamber surrounding the extension of the opening of thevaporizer I and communicating with the atmosphere. Preferably there willbe provided a cylinder 1*,of gauze or perforated metahthrough which theair must pass to reach the interior of the vaporizer I.

L is a conduit or pipe forming a continuation of the passage-way in theprojection II and at its lower end projecting into the vapor izer I.

M is abent tube entering a tapped opening in the cylinder-castin g, tothe outer extremity of which there is coupled or otherwise attached anignition-tube H. The opening in which the tube M is screwed is continuedthrough the cylinder-walls and enters that end of the cylinder to whichthe mixed vapor and air are admitted.

The ignition-tube may be of any suitable material which may be subjectedto a high degree of heat; but preferably I will use porcelain.

N is a bu rner-body for holding a combustible liquid. It is providedwith upwardly-extending tubes N N, which at their upper extremities areformed or provided with a clownwardly extending loop or bend N whosemembers are provided with perforations on their upper surfaces, throughwhich issues a combustible fluid constituting the heater for thevaporizer l. The ignition-tube M will also be preferably locatedimmediately below the vaporizer to receive the heat from this heater.This formation of the upwardly-extending tubes N N and thedownwardly-extending bend N is especially desirable, as if a liquid isused to supply the heater it will be vaporized by the heat of the flameand is sue in the form of gas from the perforations in the bend N Thegas issuing from the perforations may be mixed with air previous to itsignition, if found desirable.

During the operation of the engine the ignition-tube M is to be kept ata high temperature by the burning gas.

As the governor G is designated to operate the slide IE only on itsbackward movement, a stop may be carried by the block 0 and project intothe path of the arm 0 to prevent any unnecessary backward movement ofthe arm. It is here shown to be in the form of a screw provided with alock-nut o.

The operation of the engine may be described as follows: As thereciprocating rod l3 moves to the left in Fig. 1, it carries thegovernor G to a position in which the arm 0 contacts with the stop 0. Onthe movement of the rod to the right, arm 0 is swung upon its pivot C tothe left, the amount of this swing ing movement or its a-ngularity withthe vertical depending upon the rapidity of movement of the rod B.Consequently if the engine is running at a high speed or above that towhich it may be adjusted the arm 0 will. be elevated so high that thecatch c will not engage with the lug c and the slide E will remainundisturbed; but if: the movement of the engine is below the normal thearm 0 will swing but a slight distance to the left, the catch c willengage with the lug c and the slide E will be pulled forward. As aresult, piston. G will be depressed and fluid will be injected into thevaporizer to supply the cyl' inder of the engine.

Mixed vapor and air are drawn into the engine-cylinder by the movementof the piston through. the passage-way 1, the valve 1 being momentarilylifted from its seat. \Vhen the piston reverses its movement, valve 1?drops upon its seat, the mixed vapor and air are compressed and forcedinto the ignitiontube M, explosion takes place, and the piston is forcedin the reverse direction. The exhaust-valve is now opened by themovement of the rod B and the products of combustion exhausted from thecylinder.
